TYPE-WRITING MACHINE Application filed. October 13, 1906.

Specification of Letters Patent.

Patented Nov. 17, 1908. Serial No. 838,859.

To all whom it may concern:

Be it known that I, IIERMA'N L. WAGNER, a citizen of the United $tates,residing in Mount Vernon, in the county of W'estchester and Stateof NewYork, have invented certain new and useful Improvements in Type-Machines, of which the following is a spool cation. y

This invention relates principally to that class of tabulatingmechanisms for typewriting and other machines in which independentlyoperable denomination keys are provided, although certain featuresthereof may be applied to other tabulating mechanlsms.

My invention is the natureof an improvement upon the construction shownin my pending application No. 323,588 (Patent N 0. 853,280), in whichthedenomination keys are shown mounted ina row on the ends of short armswhich extend forwardly from the front bar of the paper carriage,denomination stops being rigidly connected to said arms and depressibleindependently one of another by the keys to engage column stops andplaced side by side at letter space intervals, and each key arm with itsstop forming a bail, the bails being of graduated sizes and nestedtogether in two sets, and keybearing arms diverging or fanning out ateach side of the set of stops to compensate for the greater length ofthe rows of keys.

One object of the invention is to improve and simplify the form and.nesting of the bails and to avoid faulty action thereof upon 'thedepression of the keys. I place all of the keys directly upon thestop-arms, so that in each of the two sets of bails are comprised alarge bail carrying a key upon its stop-arm and successively smallerbails within said larger bail and forming a regular nest, each stop-armcarrying a key. The keys are carried upon extensions which diverge tothe right and left of thestop-arms, and means are added directly beneaththe keys for arresting them to avoid distortion of the bails in action.

In the preferred form of the present invention one or more stops areintroduced between the two sets of bails to further simplifytheconstruction and economize room; said additional stop-arms beingsingle arms and pivoted upon a common axis of the bails and carryingkeys at their forward ends.

I is a plan of the front upper portion of an Underwood typewritingmachine provided with my improvements in their preferred form. Fig. 2 isa sectional side elevation illustrating the operation of setting adenomination key and simultaneously releasing the carriage. Fig. 3 is aperspective view of two of the denomination-keys and stops. Fig. at is adiagram showing the same arrangement of denomination mechanism, as atFig. 1', and showing the two middle stop-arms as lengthened and formedinto-bails.

The usual cylindrical platen is illustrated at 1, and is mounted upon ashifting platen frame, (not shown), the latter mounted in the 11511211manner upon a carriage comprising side bars 2 and front bar 4. Thecarriage is propelled by the usual spring barrel 5 and strap 6, and isprovided with a letter spacing rack 7 to mesh with a pinion 8, thelatter formin part of the usual escapement or letter feeding mechanism.Saidpair of arms 9 hinged at 10 upon the carriage frame and providedwith a forwardly extending depressible arm 11, so that vby depressingthe arm, the rack may be raised clear of the pinion 8, and the carriagemay run along freely under the influence of the propelling spring Thecarriage has a front roll 13 running upon a track 14.

Extending along the carriage in front of the platen is a horizontal rockshaft 15 mounted in ears 16 projecting from a bracket 17, the latter(letachably securedby screws 18 upon the top of the front carriage bar4. Said rock shaft extends through the end bar 2 of the carriage and isprovided with a short arm 19, to vibrate a lever 20, and thereby depressthe arm 11 of the rock frame 7, 9, and release the carriage. A carriagerelease bar 22 extending along the carriage in front of the keys ismounted byarms 23 and carriage may be released by the finger of theoperator at the same time that a denomination key'is depressed.

Referring to Fig. 4:, it 'will be seen that rock shaft 15 between thecollars 23 are t 0 sets of bailsfof graduated sizes, tliebai s beingnested one within another, and thesets of bails being placed side byside, each'bail:

rack is usually provided at its'ends with a.

collars 23 upon the shaft 15, so that the mounted loosely upon thecarr1age releasing 1-0.5

depressible independently of the others.

The largest bail in each set is numbered 24, the next 25, the next 26,and the remaining balls 27 and 28. Each bail comprises a pair of arms 32and 33, both arms extending forwardly from the rock-shaft 15. The arms32 are straight and parallel and mounted at letter space intervals andform a system of ten denomination-stops. The denomination keys 34 aremounted in front of the stops upon extensions 35 which diverge forwardlyfrom the bail-arms, such divergence being necessary where the keys aremounted in a in one set correspondto those in the other a: smallcompass.

outer arms of the bails return the latter. to

but are oppositely disposed, that is to say, the shortarms in one'set ofbails are upon the left while the corresponding arms in the other set ofbails are on the right of thesystem of stop arms. The smallest bail 28,whose stop-arm carries a key at the extreme end of the row of keys isnested within the next larger bail 27 which carries the next key; andthe bail 27 in turn is nested within 26 which carries the third key andis in turn nested within 25 carrying the fourth key; the bail 25 beingnested within the largest bail 24v carrying the fifth key. By means ofthis construction and thisposition of the bails, ample-length of bearingin axial direction is secured even for the smaller bails, while the endsystem of bails is kept within Springs 36 under the normal positions.All except the two middle extensions 35 are branched out from the stoparms 32 between the ends of the latter as seen be'stat Fig. 2, so thatthe outer extensions when depressed may clear the adjoining stopswhichthey-overlie as at Figs. 1

and 4; the'point-of branching being carried gradually backward from themiddle to the sides of the system, to give clearance for the Iextensions with relation to one another.

The bracket 17 is formed at its rear edge, with an upturned comb 37toguide the bailarms and the front edge of the same plate or bracket isalso bent up to form a corresponding guiding comb 38 .for the 'same'arms.

' In .0 eration, any desired denomination key 1s epressed, the finger atthe same time pressmg down the release key 22. The carriage is thendrawn along by the spring 5 until arrested by the engagement of the de-'pressed stop 32 with a column stop 40 provided upon the framework. tionkey. and release key are then relieved -of The bails- Thedenominapressure and the type keys manipulated in the usual manner,types 41 striking-as usual mounted at the front of the machine where 7they may be conveniently seen and operated, but also that they are belowthe line of vision. That is, the tabulating-mechan'ism does not comebetween the line of writing onthe platen and the eyes of the operator.

Referring now particularl to Fig. 1, it will be seen that in place ofbails 24, single stop-arms 24 are employed having forwardly divergentextensions 35 the two outer bearing the twomiddle keys34. Said mid-' 1die keys are but littleotfset from said arms 1 24 and hence the lattermaybe sufliciently 'guidedand steadied by means of the guiding combs, sothat it is .unnecessary to employ bails for these keys, whereby thetabulatin mechanism is somewhat more compacted an its'cost somewhatreduced.

Beneath the keys is an arresting bar- 43 supported bymeans of arms 44extending forwardly from the bracket 17. This stop bar. will preventundue depression of the keys and consequent distortion of an injury to'the extensions 35,. especially at. the extremities of the keyboard.

The bails 28 may in some cases be omitted and the denomin'ationallettering upon the keys changed accordingly. 1

Variations may be resorted. to within the scope of the invention, andportions of my improvements may be used without othersuv ids Having thusdescribed my invention, I I
